Shameless plug but this might be a good time to install Spegel in your Kubernetes clusters if you have critical dependencies on Docker Hub.

If it really is fully open-source please make that more visible on your landing page.

It is a huge deal if I can start investigating and deploying such a solution as a techie right away, compared to having to go through all the internal hoops for a software purchase.

How hard is it to go to the GitHub repository and open the LICENSE file that is in almost every repository? Would have taken you less time than writing that comment, and showed you it's under MIT.

After some digging - https://github.com/spegel-org/spegel/blob/main/LICENSE says MIT

What's the difference with kuik? Spegel seems too complicated for my homelab, but could be a nice upgrade for my company

Kuik: https://github.com/enix/kube-image-keeper?tab=readme-ov-file...

It's been a while since I looked at kuik, but I would say the main difference is that Spegel doesn't do any of the pulling or storage of images. Instead it relies on Containerd to do it for you. This also means that Spegel does not have to manage garbage collection. The nice thing with this is that it doesn't change how images are initially pulled from upstream and is able to serve images that exist on the node before Spegel runs.

Also it looks kuik uses CRDs to store information about where images are cached, while Spegel uses its own p2p solution to do the routing of traffic between nodes.

If you are running k3s in your homelab you can enable Spegel with a flag as it is an embedded feature.

There is a couple of alternatives that mirrors more than just Docker Hub too, most of them pretty bloated and enterprisey, but they do what they say on the tin and saved me more than once. Artifactory, Nexus Repository, Cloudsmith and ProGet are some of them.

[phillebaba]

Spegel does not only mirror Docker Hub, and works a lot differently than the alternatives you suggested. Instead of being yet another failure point closer to your production environment, it runs a distributed stateless registry inside of your Kubernetes cluster. By piggy backing off of Containerds image store it will distribute already pulled images inside of the cluster.

This looks good, but we're using GKE and it looks like it only works there with some hacks. Is there a timeline to make it work with GKE properly?

[phillebaba]

I am having some discussions about getting things working on GKE but I can't give an ETA as it really depends on how things align with deployment schedules. I am positive however that this will soon be resolved.

Google Cloud has its own cache of Docker Hub that you can use for free, AWS does as well
